I think this could be carried over to the concept that you don't need industrial goop to lose weight. Quite the contrary. I remember an acquaintance who was trying to lose weight, and on a particular day she was snacking on some kind of Atkins-style commercial drink. (Incidentally, on that same day, I decided to eat 12 servings of fruits and vegetables.) The drink had a long, long list of ingredients, all of them artificial and processed. How can your body do anything good with those?
